Resistor - chinokosha Electronics

Resistor - ndiye nyore vanzwe redhiyo-zvemagetsi mumatunhu, vane pfuma kudzivisa ichiyerera kubudikidza Magetsi. Zita chiridzwa iri rinobva Chirungu shoko muchipikisa, izvo zvinoreva - nemishonga.

The aizviti resistor ukoshi akayera muna Ohms (Ohms Ohm mamita?), Mushure musayendisiti mutemo Georg Ohm kwakaita zvakwakafukurwa, maererano izvo kurwisa redunhu ndiyo nhamba voltage redunhu ano.

In indasitiri, ivo resistors anobudiswa ne zvakasiyana chezita nemishonga ukoshi. Kune mhando huru nhatu mano aya: yatarwa shanduka, dzemwenje.

Yakamisirwa resistor - ndiwo kirasi kupfuura yakawanda zvinhu vane kugara impedance. On dzimba kuti mudziyo yakadaro iri kunzi, zvichireva resistor mhando, kuti aizviti kurwisa ukoshi zvakarurama kirasi, simba nounzenza, uye vamwe. Mashoko iyi encoded munzira dzakasiyana-siyana. Saka, unogona kuwana zvinhu izvo mashoko ose akanyorwa kushandisa ruvara Coding (matatu nomwe chitsvuku transverse zvisungo). Kuverenga tsika idzi, unofanira kushandisa chaiyo tafura, iyo inogona kuwanikwa mabhuku kana zvekushandisa tsananguro kuti zvinhu izvi. The mhando kurekodha wechipiri alphanumeric. With nzira iyi mashoko ari wakapiwa pachishandiswa zviratidzo uye digits. Nokudaro, 10 Ohm resistor ichava sezvinotevera: MLT 10R. Zvinoreva MLT mhando mudziyo.

Shanduka resistor - zano ane chaicho siyana aizviti nemishonga. Kana akadaro ichocho aripo risa nhengo (muhombe nepfundo kana sikuruu), kuburikidza paunogona kuisa zvinodiwa kurwisa ari mudziyo. In dzakadaro mano kuti aizviti ukoshi zvinoratidzwa kupenda alphanumerical chimiro - runotaurwa muganhu kubva shoma kune kunonyanyisa nemishonga ukoshi. Kwakadaro mano anoshandiswa nevakawanda kudzora uye aramu Kurongwa: sezvo matauriro chidhiraivho, zvese, vhoriyamu, Frequency Tuning ari redhiyo kugamuchira michina.

Trimmer - zano ane chaicho siyana chezita nemishonga, asi vakasiyana variables, ichi chikuva vasingakoshi. Kwakadaro zvinhu zviri zvinowanzoshandiswa zvemagetsi matunhu. Vari zvarakanyorerwa kuchinja uye kunatsiridzwa zvaida parameters pamasikiro redhiyo kana zvakarurama mano apo kutendera paradzira unhu. Vanobvumira kuti kunyatsotaura kuisa zvinodiwa nemishonga, zvichiguma soldered padenga zvisingakoshi desoldering-kugara chezita resistors kuti kusarudza achida ukoshi.

Kunze dzinokosha parameters, chero anonzi parasitic rezistorasuschestvuet noruzhinji - capacitance. Ndechipi ichi? The parasitic capacitance pamusoro resistor kazhinji duku zvikuru uye kunyanya chinhu asina kukanganiswa. Zvakakodzera kufunga chete pamasikiro mukuru-zvakarurama michina. Parasitic capacitance kuripo pakati mbambo nhengo; zvinoitika kuti yakafanana resistor soldered capacitor. Uyewo, mugaba zvingaitikawo pakati resistor uye pedyo zvikamu zviri pcb uye nhengo mamiriro.

In ichi muchidimbu chinhu ichocho akadai resistor, tinopedzisira, mamwe mashoko anogona kuwanikwa maindasitiri Electronics mabhuku.
